CC Com and BV Dra light curves
Listed in IVOA Registry (Virtual Observatory)
Based on O-C curves, we present detailed period investigations of two weak-contact binaries CC Com and BV Dra.
Description
It is found that the periods of these two binaries have varied in a cyclic variation way superposed on a secular period change. The periods and amplitudes of the cyclic variations are P_3_=23.6(+/-0.4)yr and A=0.0028(+/-0.0003)d for CC Com and P_3_=23.8(+/-0.6)yr and A=0.0029(+/-0.0003)d for BV Dra.
